Impala Theft Relearn Procedure
This procedure should work, as long as all was installed properly, or there
is not another problem with the car.
With the other problem you describe about the dash lights, you may have a
bad BCM or ignition SWITCH. And now replacement of the theft cylinder
cannot relearn because of another problem. If none of the above work to
relearn the theft, try re-installing old cylinder, then car should as it used to
before replacement.

Theft / Security Light
The security system on todays cars and trucks prevents the vehicle from being stolen. There are many
variations of the system going back to the early 1990's.
This warning could be on when the engine is running, indicating a fault has been detected in the system.
If left un repaired, there is a good possibility that the car will eventually not start.
There are several different possibilities for the cause of the warning, depending on the make / model /
year of the vehicle. Anything from a bad ignition cylinder wire, to a bad cylinder to a dad Body Control
Module (BCM).
After market (non-factory) alarm and remote start systems can cause havoc with the factory theft system,
causing this warning light, or a no start.
